Maybe a little late now, but our bunnies love pea shoots! They are ridiculously expensive to buy but very easy to grow. A box of dried peas or pea "seeds" will do, and they don't cost much. Soak overnight in water, then liberally sprinkle them over some compost (a container is fine). Cover with more compost and they should be ready in a few weeks. If you keep cutting the tops off the plants will keep growing back for a while, and I think they can be dried for storage.
